I figured some glow plugs were out cuz it had been hard to start once it started getting cold. I finnaly took them out and 6 were bad out of 8 (it would no longer start in the morning). Ive had my bus since June, so I figured I would replace all 8.

The glow plugs that I removed were several differnt brands (obviously never replaced all at the same time). However most of them were Champions "CH-84". So I went to napa and had them cross-referenced to a brand they carried.

Bought 8 new glow plugs, and installed them. Engine started like she never started before, one turn on a cold day, and I was good to go. It was nice.

So a few days go by, and I noticed its hard to start again. Although its still easier than it was. I figured I would check the glowplugs again. Although I havnt removed them yet, I think about 4 or 5 of them are bad!!!!

I JUST BOUGHT THEM! this is so annoying. What could be burning out my plugs??

The relay? the Glow Plug Module?
Or were they just shitty plugs, and I should take em back to the store?

If I had thought the module was bad before hand. I would have bought the other deal this guy had which was 8 plugs and the module for $130. (not a bad deal considering most places I was quoted about that price for just the module)
